Title: Method of producing glass fibre mats
IPC: D04H1/4218
Filed: 1973-11-29
Abstract: 1387549 Resin-fibre mat KAO SOAP CO Ltd 29 Nov 1973 [29 Nov 1972] 55475/73 Heading D1R A glass fibre mat is bound with an unsaturated polyester resin having a softening point of 80 to 130C and obtained from A moles of an α,# ethylenically unsaturated dibasic acid or anhydride, where A has the value 0.3 to 0.7, (1-A) moles of trimellitic acid or trimellitic acid anhydride and 0.8 to 1.5 moles of a diol. Optionally 0 to less than 2 (1-A) moles of a non ethylenically unsaturated dibasic acid may be present. Specified unsaturated acids/anhydrides are maleic acid, fumaric acid, itaconic acid and maleic anhydride. The dial may be ethylene glycol, propylene glycol, neopentyl glycol, butanediol, trimethyl pentanediol and hydrogenated bisphenol. The non ethylenically unsaturated acid/anhydride may be adipic acid, succinic acid, isophthalic acid phthalic anhydride and tetrahydrophthalic anhydride.  The esterification reaction may be carried out at 150 to 220C. Preferably the α, # ethylenically unsaturated dibasic acid or acid anhydride and the non-ethylenically unsaturated dibasic acid, if used, are reacted with the diol to prepare a polyester having an acid number of less than 10, trimellitic acid anhydride is added and the reaction continued until the hardening time of the mixture comes within the range of 20 to 60 seconds. The mat is formed by droping chopped glass strands uniformly onto a perforated plate, spraying the layer with water, applying the binder as a ground powder uniformly to the mat, repeating the cycle 3 times, and heating the 4 layer mat in a 200C oven for 20 minutes. The binder comprises 3 to 4% by wt. of the fibres. The binder is substantially insoluble in styrene at this stage, i.e. with a 12.5 x 10 cm sample immersed in a tank of styrene and a 100 gm weight hung from its lower end the mat does not break (due to dissolution in styrene) for at least 6 minutes. The mat may be compression moulded under heat with other mats to form a laminate. Comparative example 1 discloses applying the binder as a solution in water containing triethylamine, comparative examples 2 and 3 describe the use of bisphenol A polyester resins, benzoyl peroxide being incorporated into the binder of comparative example 2.

[Also in Division F2E] A towing coupling comprises a draw-tube 20 connected with a ball socket 10 and slidable in a housing 26, there extending between the socket and the rear part of the housing a damper 56, and forward movement of tube 20 in the housing being limited by a nut 22 during towing, the coupling also including an overrun brake mechanism consisting of a pivoted lever 82 contacted and rotated clockwise by the nut 22 during over-run to actuate brake rod 90, this mechanism being rendered inoperable during reversing of the coupled vehicles by utilizing to preventing rearward movement of tube 20 and hence nut 22, a reversing stop 120 which during over-run is moved from the rearward path of the rod 22. The reversing stop 120 is connected to a deflector member 92, for over-run braking, by a spring loaded latch member 160, the stop 120 and member 92 both being pivoted at 86. During over-run braking a roller 146 mounted on member 92 is moved downwardly hence moving the stop out of the path of nut 22, but for reversing a solenoid 168 is activated withdrawing the latch 160 so that the stop 120 prevents the over-run brake operating. A hand brake 104 operating on brake lever 82 can be retained "on" by a pawl and racket mechanism 110, 98.

Abstract: 1,241,325. Watering plants. R. CRANE. 5 Aug., 1969 [7 Aug., 1968; 29 Nov., 1968], Nos. 37757/68 and 56871/68. Headings AID and A1E. [Also in Division G1] In an apparatus for distributing water, valves 16 between the supply 26 and nozzle outlets 34 are controlled by a photo-electric detector cell 18. The detector comprises a photo-transistor VT1 housed in an aluminium casing sealed by a silicon rubber gasket 46 and epoxy resin joint 48 (Fig. 2, not shown) and controls the water supply sequentially to spray stands 12A, 12B and 12C in inverse proportion to the light intensity. Current from the phototransistor VT1 charges capacitor C1 until, after a time dependent on variable resistor VR1, a unijunction transistor UJT1 fires : the watering cycle rate being dependent on the rate of firing of UJT1. Firing of UJT1 triggers a silicon-controlled rectifier SCR2 to operate the solenoid SOL 2 controlling one valve 16. The valve 16 remains open while capacitor C6 charges up at a rate dependent on variable resistor VR3 (as shown) until the unjunction transistor UJT3 fires thereby switching on SCR3 operating solenoid SOL 3 of the second watering stand where-upor the capacitor C7 commutates SCR2 into cut-off, closing SOL 2. The firings of UJT1 by the phototransistor VT1 thus sequentially operates the solenoids SOL 2, SOL 3, SOL 4 of stands 12A, 12B, 12C respectively for adjustable periods.

Abstract: 1,242,034. Photo-metric analysis. UNITED STATES ATOMIC ENERGY COMMISSION. Nov.24, 1969 [Dec. 18, 1968], No.57351/69. Heading G1A. [Also in Division G2] In a photo-metric solution analyzer the samples are contained in cuvettes 9 located in the periphery of a power-driven rotor assembly 1, each liquid sample being formed from reagents and reactants which are placed in separate chambers 15 when the rotor is at rest but which are mixed together and urged outwardly through the passage 16 into the cuvette when the rotor is rotated. The transmissivities of the separate samples are displayed on a CRO 25, Figs. 3-5 (not shown), which is connected to the output of a photo-multiplier 20. The chambers 15 are located in a detachable plate, and after an initial mixing and consequent analysis of a solution in each cuvette, a new plate 15 containing a different combination of reagents and reactants may be introduced, and the effect of these new reagents and reactants on the sample in the corresponding cuvette may be determined photo-metrically by again rotating the rotor. To ensure adequate mixing, the rotor is first accelerated rapidly to transfer liquid to the cuvettes, is then decelerated rapidly to facilitate mixing, and finally reaccelerated to a suitable speed for testing. The apparatus may be applied to the determination of a common substance in a multiplicity of discrete samples.
